  • Determining whether one array contains the contents of another array in ruby

    - by Andrew Grimm
    In ruby, how do I test that one array not only has the elements of another array, but contain them in that particular order? correct_combination = [1, 2, 3, 4, 5] [1, 5, 8, 2, 3, 4, 5].function_name(correct_combination) # => false [8, 10, 1, 2, 3, 4, 5, 9].function_name(correct_combination) # => true I tried using include, but that is used to test whether [1,2,3].include?(2) is true or not.

  • JavaScript sorting array from nested array?

    - by Tim
    I have an array: letterFrequency = [["a", 12], ["b", 25], ["c", 34], ["d", 1], ["e", 35], ["f", 8], ["g", 7], ["h", 67], ["i", 35], ["j", 0], ["k", 53], ["l", 0], ["m", 0], ["n", 3], ["o", 0], ["p", 0], ["q", 3], ["r", 153], ["s", 0], ["t", 0], ["u", 15], ["v", 0], ["w", 0], ["x", 3], ["y", 0], ["z", 0]] and I want to sort it in descending order based on the number within the nested array i.e. letterFrequency[i][1]. So I want the most popular letter to be first. How would I do this?

  • combinations of sizes for shipping

    - by Eadz
    Hi there, I've got a bunch of products with sizes to ship and I need to find out the cheapest rate. Given a shipment made out of sizes, say [1,3,3,5] I need to decide how to ship - all together or separate. However it's not as simple as [1,3,3,5] or 1 & 3 & 3 & 5, i need all of the possible combinations something like: [ [[1,3,3,5]], ( 1 shipment ) [[1],[3,3,5]], ( 2 shipments ) [[1,3],[3,5]], ( 2 shipments ) [[1,3,3],[5]], ( 2 shipments ) [[1,5],[3,3]], ( 2 shipments ) [[1,3],[3],[5]], ( 3 shipments ) [[1],[3],[3],[5]] ( 4 shipments ) ] ( etc - many more i assume ) I've tried combinations from the facets gem but it's not quite what i'm after, and I'm not sure how else to approach this problem. I understand it probably has a name and a solution if only I knew the name :) I understand there could be a lot of combinations, but the initial array of sizes won't be larger than 7 or so. Thanks in advance!

  • La fondation Eclipse sort Eclipse Juno 3.8 /4.2, une double version de l'EDI riche en nouveautés

    La fondation Eclipse sort Eclipse Juno 3.8 /4.2 La fondation Eclipse vient de sortir la version Juno d'Eclipse. Une nouvelle version d'Eclipse est disponible. Elle porte le nom de Juno. Cette version est en fait une double version, puisque nous avons droit à la fois à la version 3.8 ainsi qu'à la version 4.2. Il faut savoir que la version 3.8 est la dernière "version" pour Eclipse 3.XX. Des versions de maintenance sont prévue pour la 3.8, mais aucune version majeure supérieure n'est prévue dans les 3.XX. Cela tient d'une volonté de la fondation Eclipse de basculer majoritairement sur les versions 4.XX. La version 4 (précédemment baptisé e4) d'Eclipse est en développement depuis 4 ans et const...

  • Lwjgl or opengl double pixels

    - by Philippe Paré
    I'm working in java with LWJGL and trying to double all my pixels. I'm trying to draw in an area of 800x450 and then stretch all the frame image to the complete 1600x900 pixels without them getting blured. I can't figure out how to do that in java, everything I find is in c++... A hint would be great! Thanks a lot. EDIT : I've tried drawing to a texture created in opengl by setting it to the framebuffer, but I can't find a way to use glGenTextures() in java... so this is not working... also I though about using a shader but I would not be able to draw only in the smaller region...

  • Double click executable file and nothing happens

    - by Ralf Tiede
    I'm trying to install a game for Linux called Myth 2. Autorun doesn't run when I insert the CD. When I double-click or right-click and the select "Open" on the Setup file, a box appears saying that it's an executable file, and what I want to do. I click on "Run", but nothing happens after that. I checked the permissions, and it allows it running the executable. How do I install this game? Please break down instructions as much as possible, I'm not used to using commands and Terminal. ;)

  • Stacked Launcher Item Double Click Behaviour on Alt-tab

    - by Brandon Bertelsen
    Let's say that you have multiple firefox windows open. What you see happen is an additional arrow points to it's icon in the launcher. However, if you double click the icon, it displays all of the windows in a spread out fashion, similar to the behaviour from pushing Super + W, but only for that program group. Is it possible to make this window spreading behaviour occur with alt-tab? PS: No idea what tags I should use, or if the language (jargon) in the title or question is appropriate.

  • Tab navigation and double content

    - by Guisasso
    I have a website in which i use tabs to navigate between pages. For example, page a displays A as an active tab and B and C background tabs. If the visitor gets to the website via page B, i also would like to display to page d, but not a and c. Question: I know i can just create index2 for b for example, so when the visitor gets to b from a, i display a,b,c and index1 when visitor gets to b from d for example. Is that a bad practice? I know double content isn't good, but in which other way can i or should i approach this problem? The tab navigation i designed uses < li and id tag do display active tab, defined in the < body tag.

  • C# double &amp; nary for loops

    - by MarkPearl
    Something that I wasn’t aware was possible in C# was double for loops… they have the following format. for (int x = 0, y = 0; x < 10; x++, y=x*2) { Console.Write("{0} ", y); } Console.ReadLine(); This would give you the following output… 0 2 4 6 8 10 12 14 16 18 In fact you can use as many variables as you want, the following would also be valid… for (int x = 0, y = 0, z = 10; x < 10; x++, y=x*2) { Console.Write("{0} ", z); } Console.ReadLine();

  • Double X-screens on one monitor

    - by user75226
    I have two monitors connected currently, my laptop display and an old dell monitor. For some reason one monitor (the dell) has double everything (it will make sense when you see the image). I think it came about when one day I tried using separate x-screen instead of just twin view for a specific reason I don't remember why (I was trying to get the Menu bar to show on my laptop monitor instead of the Dell I believe, it only shows up on the left-most monitor it seems) but anyhow I was wondering if anyone can help me fix this issue. Thanks.

  • 2 Google Tag Manager containers = double triggers?

    - by fred
    I have a Joomla website with existing analytics done by a GTM tag and I need to add another image tag (1x1 pixel) from a separate GTM container. I set the event name for the additional GTM container to a different name from from the existing GTM container (default 'gtm.js') so that the new tag only fires under the specified event. The new container tested out fine in a blank HTML page, but when it is put in the website, it ends up firing twice. I know that because Firebug showed 2 1x1 pixels being loaded and I mark each request with a randomly-generated UID to distinguish them on the server side. I suspect this being caused by having multiple GTM container tags but want to check whether anyone has run into this problem before? As of now, I could not verify nor fix the double counting problem.

  • Ubuntu 12.10, mouse double click by itself

    - by Ribi
    I updated ubuntu 11.10 some time ago and I had a problem with my mouse. When I click somewhere it would double click by itself. It was pretty anoying as I would start 2x my application almost each time. Then, some update came and the mouse was better. But now, I updated to 12.10 and it does the same thing again. I'm using an Logitech MX Revolution. I don't know what I can do to resolve this problem? Thanks

  • Double equals (Not equality) during assigning Java

    - by FabianCook
    When I tried searching this I would just get things on equality. When I was reading through some documentation for navigation in Android I had come across something I had never seen before. I came across this: mTitle = mDrawerTitle = getTitle(); It almost looks like something you can do in JavaScript where you can take the first not-null variable and assign it to a variable. In JavaScript I would do this: mTitle = mDrawerTitle || getTitle(); And it would return the first not null, in Java, is this double equals usage the equivalent in Java? What is this type of expression called?

  • Multidimensional array with unequal second dimension size using malloc()

    - by user288422
    Hello, I am playing around with multidimensional array of unequal second dimension size. Lets assume that I need the following data structure: [&ptr0]-[0][1][2][3][4][5][6][7][8][9] [&ptr1]-[0][1][2] [&ptr2]-[0][1][2][3][4] int main() { int *a[3]; int *b; int i; a[0] = (int *)malloc(10 * sizeof(int)); a[1] = (int *)malloc(2 * sizeof(int)); a[2] = (int *)malloc(4 * sizeof(int)); for(i=0; i<10; i++) a[0][i]=i; for(i=0; i<2; i++) a[1][i]=i; for(i=0; i<4; i++) a[2][i]=i; } I did some tests and it seems like I can store a value at a[1][3]. Does it mean that rows in my array are of equal size 10?

  • String to array or Array to string tips on formats, etc

    - by user316841
    hi, first of all thanks for taking your time! I'm a junior Dev, working with PHP + mysql. My issue: I'm saving data from a form to my database. From this form, there's only need to save the contacts: Name, phone number, address. But, it would be nice to have a small reference to the user answers. Let's say for each question we've got a value betwee 1 and 4. Since there's no need to create a table just for it, because what's needed is just the personal contacts. I'm thinking of recording each question/answer, as a letter and its correspondent value. Example (A2, B1, C5, D3, etc). My question is: Is there a format I could afterwards, handle easily ? Convert to array (string to array) in case the client change ideas, and ask this data, placed in table columns ? Just to prevent this situation! Example, From (A2, B1, C5 ) to array( "A" = "1", "B" = "1", "C" = "5" ) For now I guess, Regex is the answer, but it's allways hard to figure it out and I'm allways getting in troubles =) Thanks!

  • Generating All Permutations of Character Combinations when # of arrays and length of each array are

    - by Jay
    Hi everyone, I'm not sure how to ask my question in a succinct way, so I'll start with examples and expand from there. I am working with VBA, but I think this problem is non language specific and would only require a bright mind that can provide a pseudo code framework. Thanks in advance for the help! Example: I have 3 Character Arrays Like So: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] I would like to generate ALL possible permutations of the character arrays like so: XA1 XA2 XA3 XA4 XB1 XB2 XB3 XB4 YA1 YA2 . . . ZB3 ZB4 This can be easily solved using 3 while loops or for loops. My question is how do I solve for this if the # of arrays is unknown and the length of each array is unknown? So as an example with 4 character arrays: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] Arr_4 = [a,b] I would need to generate: XA1a XA1b XA2a XA2b XA3a XA3b XA4a XA4b . . . ZB4a ZB4b So the Generalized Example would be: Arr_1 = [...] Arr_2 = [...] Arr_3 = [...] . . . Arr_x = [...] Is there a way to structure a function that will generate an unknown number of loops and loop through the length of each array to generate the permutations? Or maybe there's a better way to think about the problem? Thanks Everyone!

  • Modifying NSMutableDictionary from a single index format into nested (array within array)

    - by Michael Robinson
    I need to take the member ID off the top of this and create an array inside that contains the rest of the JSON return. Here is my JSON return. [{"F_Name_VC":"Frank", "L_Name_VC":"Johnson", "userid":"18", "age":"23", },] After it is json-deserialized it looks like this: I need convert it to be transformed into this, with children sub-array: Someone else posted a similar question but without the fact that it was coming from a JSON deserialization. There were two answers but no conclusion to the question. (Answer 1): NSDictionary *item1 = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@" member",[NSNumber numberWithInt:3],nil] forKeys:[NSArray arrayWithObjects:@"Title",@"View",nil]]; Answer (2): NSMutableArray *Rows = [NSMutableArray arrayWithCapacity: 1]; for (int i = 0; i < 4; ++i) { NSMutableArray *theChildren = [NSMutableArray arrayWithCapacity: 1]; [theChildren addObject: [NSString stringWithFormat: @"tester %d", i]]; NSString *aTitle = [NSString stringWithFormat: @"Item %d", i]; NSDictionary *anItem = [NSDictionary dictionaryWithObjectsAndKeys: aTitle, @"Title", theChildren, @"Children"]; [Rows addObject: anItem]; } NSDictionary *Root = [NSDictionary withObject: Rows andKey: @"Rows"]; Here is my JSON return and save code: NSData *jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding]; NSError *error = nil; NSDictionary * dict = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error]; if (dict) { rowsArray = [dict objectForKey:@"member"]; [rowsArray retain]; } Thanks in advance. Every tutorial on JSON only shows a simple array being returned, never with children..It's driving me crazy trying to figure this out.

  • Uninitialized array offset

    - by kimmothy16
    Hey everyone, I am using PHP to create a form with an array of fields. Basically you can add an unlimited number of 'people' to the form and each person has a first name, last name, and phone number. The form requires that you add a phone number for the first person only. If you leave the phone number field blank on any others, the handler file is supposed to be programmed to use the phone number from the first person. So, my fields are: person[] - a hidden field with a value that is this person's primary key. fname[] - an input field lname[] - an input field phone[] - an input field My form handler looks like this: $people = $_POST['person'] $counter = 0; foreach($people as $person): if($phone[$counter] == '') { // use $phone[0]'s phone number } else { // use $phone[$counter] number } $counter = $counter + 1; endforeach; PHP doesn't like this though, it is throwing me an Notice: Uninitialized string offset error. I debugged it by running the is_array function on people, fname, lname, and phone and it returns true to being an array. I can also manually echo out $phone[2], etc. and get the correct value. I've also ran is_int on the $counter variable and it returned true, so I'm unsure why this isn't working as intended? Any help would be great!

  • Multi-dimensional array edge/border conditions

    - by kirbuchi
    Hi, I'm iterating over a 3 dimensional array (which is an image with 3 values for each pixel) to apply a 3x3 filter to each pixel as follows: //For each value on the image for (i=0;i<3*width*height;i++){ //For each filter value for (j=0;j<9;j++){ if (notOutsideEdgesCondition){ *(**(outArray)+i)+= *(**(pixelArray)+i-1+(j%3)) * (*(filter+j)); } } } I'm using pointer arithmetic because if I used array notation I'd have 4 loops and I'm trying to have the least possible number of loops. My problem is my notOutsideEdgesCondition is getting quite out of hands because I have to consider 8 border cases. I have the following handled conditions Left Column: ((i%width)==0) && (j%3==0) Right Column: ((i-1)%width ==0) && (i>1) && (j%3==2) Upper Row: (i<width) && (j<2) Lower Row: (i>(width*height-width)) && (j>5) and still have to consider the 4 corner cases which will have longer expressions. At this point I've stopped and asked myself if this is the best way to go because If I have a 5 line long conditional evaluation it'll not only be truly painful to debug but will slow the inner loop. That's why I come to you to ask if there's a known algorithm to handle this cases or if there's a better approach for my problem. Thanks a lot.
